+## FastCGI script
+
+This is my FastCGI script I wrote to launch Rophako. Important things to note:
+
+* The shebang line points to the Python binary in my virtualenv.
+* I modify sys.path and chdir to my git checkout folder for Rophako.
+* The `ScriptNameStripper` allows `mod_rewrite` to work best. Without it you'll
+  sometimes get URL paths like `/fcgi/index.fcgi/blog/entry/...` etc. from Flask
+  because that's what it thinks its path is.
+
+```python
+#!/home/kirsle/.virtualenv/rophako/bin/python
+
+import os
+import sys
+sys.path.append("/home/kirsle/git/rophako")
+os.chdir("/home/kirsle/git/rophako")
